I have a MacBook Pro Catalina. I'm using Studio One 4 and it is completely updated. The interface is a scarlett 4i4. I have not used Studio one for several months and I usually use audio instead of the sounds found on the software, so this could have happened earlier than that. I went to mess around with that kind of stuff today, but under Impact the only sound available just says default and doesn't make any noise. I try to revisit old tracks I've put together when it worked and now all the drum beats are gone and Impact just says "sample missing" all over it.
